Abstract

A.O.G. Wentworth No. 1 Well was located in the Murray Basin, approximately 20 miles north of Wentworth, New South Wales. The well was drilled by W.L. Sides and Son Pty Limited for Australian Oil and Gas Corporation Limited to a total depth of 2081 feet. Drilling commenced on 8th September, 1961, and was completed on 14th October, 1961. A programme of coring and electric logging using a Widco unit was carried out, but no perforating, squeeze cementing, or testing operations were undertaken. The well was drilled to determine the nature of the sediments immediately beneath the Tertiary sequence, with particular reference to a refractor at a calculated depth of 1650 feet. This was thought to be basement before drilling started, but it was not identified during logging. The well penetrated 192 feet of Quaternary sands and grits; 1081 feet of Tertiary sands, silts, clays, marls, and limestones; 331 feet of Lower Cretaceous sediments, including Roma Formation Equivalents; 451 feet of Permian sandy mudstones; and bottomed in conglomerate of possible Permian age. No shows of hydrocarbons were observed during the drilling operation. In the New South Wales part of the Murray Basin, Lower Cretaceous sediments had not been previously recorded, and Permian sedimentation had been recorded in only one area, between Oaklands and Coorabin, some 250 miles east of Wentworth No. 1 Well. The off-structure drilling operation at A.O.G. Wentworth No. 1, New South Wales, was subsidized under the Petroleum Search Subsidy Act I!lS!l, from surface to total depth.
